Anyone done any RGB LED project's?

I have the RGB bug I want to start some RGB LED project's, RGB stands for "Red "Blue
Green.
With RGB Led's you can blend and create custom colors. I see there is no shortage of RGB products. They are becoming More and More popular day by day.
Kind of like how when flat screen first came out they were 5 grand now they are very affordable.

I was wondering if anyone has done any projects and could recomend a good controler and a Amp/Repeater.

Here are some examples of What RGB LED's look like and can do.
